Description

Aerobic granular sludge intensified dewatering equipment and method Technical Field The invention relates to the technical field of sewage treatment, in particular to aerobic granular sludge reinforced dehydration equipment and method. Background Aerobic granular sludge is a microorganism aggregate which is spontaneously formed under aerobic conditions and has a compact structure, and is different from the traditional flocculent activated sludge, and the aerobic granular sludge does not need carrier fixation and forms granules by means of the agglomeration of microorganisms. Due to the microbial metabolism and the water purification process, the aerobic granular sludge can generate surplus sludge after running for a period of time in the sewage treatment system, and the sludge is subjected to dehydration treatment so as to reduce the volume and the weight, facilitate transportation and treatment, reduce the risk of secondary pollution, and realize resource utilization of the dehydrated aerobic granular sludge. The utility model discloses a sludge dewatering plate-and-frame filter press in publication No. CN110482824A, including bracing piece and mounting bracket, the top fixedly connected with support frame of bracing piece, fixedly connected with hang plate on the support frame, install conveyer on the mounting bracket, conveyer sets up in hang plate below, conveyer below still is provided with the sewage collecting box, still fixedly connected with girder on the support frame, girder one end fixedly connected with thrust plate, other end fixedly connected with frame, the upper end fixed mounting of mounting bracket has drive arrangement and hydraulic pressure station, fixedly connected with communicating pipe on the hydraulic pressure station, communicating pipe is kept away from hydraulic pressure station one end fixedly connected with on the pneumatic cylinder, pneumatic cylinder fixedly connected with frame, pneumatic cylinder upper end fixedly connected with manometer, still telescopic connection has the hydraulic rod on the pneumatic cylinder, pneumatic cylinder is kept away from pneumatic cylinder one end fixedly connected with on the pressure plate, be provided with the filter plate frame between pressure plate and the thrust plate, filter plate frame and girder phase-match, still fixedly connected with sewage injection pipe on the thrust plate. The device is through setting up the filtration formula conveyer belt on conveyer to be provided with the filtration hole on the filtration formula conveyer belt, after the filter-pressing device of top accomplishes the filter-pressing of sewage or mud, open the tap on the filter-pressing plate frame lateral wall, discharge the water in sewage or the mud that accomplishes solid-liquid separation work from tap. However, in the scheme, in the operation flow of the filter press for dewatering sludge, the sewage to be treated is firstly led into the gaps between the filter pressing plates and frames, after the sewage is completely distributed, the water in the sludge is driven to pass through the filter cloth in a high-pressure extrusion mode to realize solid-liquid separation, and finally, a filter cake with the water content meeting the requirement is formed between the filter pressing plates and frames. However, in the actual operation process, if the filter cloth model is not matched with the characteristics of the sludge, the sludge conditioning link does not reach the expected treatment effect, or the filter cloth is not thoroughly cleaned in time after being used, the problem that the filter cake is difficult to naturally drop off is extremely easily caused, even if a vibrating mechanism is additionally arranged on equipment in part of the prior art, the problem that the filter cake is separated from the filter cloth is difficult to completely solve by utilizing the vibrating effect, a certain amount of filter residues still adhere to the surface of the filter cloth after the filter cake drops, and the residual filter residues block the filter pores of the filter cloth, so that the efficiency and the treatment effect of the subsequent sludge dewatering operation are adversely affected. Disclosure of Invention The invention provides aerobic granular sludge strengthening dehydration equipment and method, and aims to solve the problems that filter cakes are difficult to fall off and filter residues block pores to influence dehydration efficiency when a filter press is used for processing sludge in the related art.
